pulverized by the smooth cylindrical surface thereof, vand thus thefunctions commonly performed by two separate field implements aresecured in a single one, effecting thereby a great saving in first cost,and greatly facilitating the operation of breaking and pulverizing thesoil.l

In the accompanying drawings, Figure 1 is a side elevation of myimproved held-roller and harrow, the lever which adjusts the shaft ftion of the same.

of one cylinder armed with harrow-teeth being shownby full lines for onepositionV of the teeth, and by dotted lines for the other posi- Theteeth in this view,as well as in Fig. 2, are adj usted for protrudingthrough the roller at points Where it touches the soil. Fig. 2 isa'vertical longitudinal section of the combined rolling and harrowingmachine, the parts being in the position shown by full lines in Fig. 1.Fig. 3 is a similar section to Fig. 2,with the lever reversed inposition and the harrow-teeth set so. Aas not to protrude through theroller at the points where the roller touches the soil; and Fig. 4 isavertical section in the line :we of Fig. 1, showing the field-rollerand harrow in longitudinal section, and illustrating the crank oreccentric mechanism by which the teeth of the harro'w are adjusted soasto .protrude through the roller at points below the axis of roller whenit is desired to perform the operation of harharrow-teeth b, both ofsaid cylinders being applied to a crank-axle, B, so as to looselyrevolve thereon when the machine isin the act of use. The innercylinder,l A', is provided withradial arms, as c c', extending from hubsc2 to the inner periphery of the cylinder, and thereto attached in anysuitable manner. The cylinder A is thus properly supported upon thecrank-axle B, betweenthe crank-arms 030.3 of said crank-axle, as shown,and may revolve aroundl and upon the same when the machine is in use.The outer cylinder, A, is provided with hubsor bearings d d, throughwhich the outer end portions, e e', of the crank-axle B pass. The twocylinders are applied within a transporting-frame composed of a frontbar, f, a rearA bar, f', and side bars, f2, the axle B being made topass through the side bars/f2,

as indicated in Fig. 4, and thus when a team is harnessed to thedraft-pole h of said frame the cylinder A will be rotated bytractoncontact with the ground. This cylinder, as shown in the figures, isprovidedwith oblong slots b', through a series of which a series of theharrow-teeth b are made to project at points either above thelongitudinal axis of the roller A or at points below said axis,according as the crank-axle B is turned by its leverL This lever L is soapplied rigidly tothe crank-axle B that when it is made to assume theposition shown in solid lines in Fig. l the harroW-teethl of the innercylinder, A', will be projected through the slots b of the outercylinder, A, as shown Vin Figs. l, 2, and 4, and thus perform the workof a harrow in the ground over which the machine is drawn; and when saidlever is reversed into the position indicated in dotted'lines in Fig. lthe teeth Z) will project through the slots b of the cylinder only atpoints abovethe longitudinal axis of the cylinder A, as indicated inFig. 3, thus leaving the cylinder A at its point of contact with theground to perform the work of a land-roller; and 'in either case thecylinder A will be made to rotate simultaneously with the rotation ofthe cylinder Aby `reason of the projection of the harrow -teeth throughthe slotsr b of the cylinder A. In this manner the machine may, at thewill of the operator, be converted from aland-roller into a harrow, orfrom aharrow into a land-roller.

IOC

Any convenient device which will admit of a reversal of the position ofthe lever L may be adopted for holding the lever temporarily 1n place,as desired.

I ani aware thatin Letters Patent No. 181,976 spades have been appliedto a roller and forced out beyond the periphery of said roller byeccentric slots or guideways, and also drawn into the roller by saidWays, further, that in said patent certain ineans are shown for adaptingthe spading-inaehine for rolling land; but this patent does not show acombined harrow and iield-roller; nor does it show a combination ofsiinple devices, such as I have shown and described.

I also ain aware that in Letters Patent No. 229,106 a cornstalk-cutteris shown and -de scribed. This stalk-cutter was never designed as aharrow, nor is there any suggestion that it might be used as a combinedbarrow and field-roller.

I do not claim constructions and combinations shown in either of theabove-mentioned patents; but v -W'hat I do claim as my invention, anddesire to secure by Letters Patent, is- The combination of barrow-teethapplied to a cylinder, A', fastened to a crank-axle, B, which isprovided with a reversing-lever, L, and a iield-roller, A, having holesin its periphery for the barrow-teethl to Work in back and forth whilethey are being reversed by the lever, said roller heilig hung loosely onthe axle B, and surrounding the cylinder A, substantiall y as and forthe purpose described;
